Can I drink tea after receiving the long-acting paliperidone palmitate injection?
After receiving the long-acting paliperidone palmitate injection, it is acceptable to drink a moderate amount of weak tea. Light tea does not cause direct adverse reactions with the medication, nor does it affect drug absorption or efficacy. However, you should avoid strong tea or excessive tea consumption. If you experience symptoms such as palpitations, insomnia, dizziness, or fluctuations in your psychiatric symptoms after drinking tea, seek medical attention promptly.

The long-acting paliperidone palmitate injection works by slowly releasing medication through intramuscular injection, regulating the balance of central nervous system neurotransmitters. The components in light tea, such as tea polyphenols, do not interfere with this process or alter the drug's metabolic pathway in the body, so moderate tea consumption will not reduce the drug’s effectiveness.
However, strong tea contains higher levels of caffeine and theophylline. Excessive intake may stimulate the central nervous system, leading to anxiety, irritability, and sleep disturbances. These effects may compound the central nervous system-related side effects potentially caused by the long-acting paliperidone palmitate injection, increasing the risk of discomfort and undermining stable control of psychiatric symptoms.
When drinking tea, choose only weak tea, avoid drinking it on an empty stomach, limit intake to no more than two cups per day, and ensure at least a 2-hour interval between tea consumption and the injection. Avoid strong or cold tea, and pair your diet with light, easily digestible foods to help your body adapt to the medication.
